Abstract

The utility model discloses a sealing structure for a transmission shaft of a swing granulator, comprising a main transmission shaft, a first sealing member and a second sealing member, an auxiliary shaft being installed on one side of the main transmission shaft, a rotating plate being installed on the outside of the auxiliary shaft, a screw hole for connecting the second sealing member being opened on the surface of the auxiliary shaft, the first sealing member comprising a sealing sleeve and a first sealing pad, the sealing sleeve being sleeved on the outside of the main transmission shaft, the first sealing pad being sleeved on the gap between the main transmission shaft and the sealing sleeve, and the second sealing member being threadedly connected in the screw hole on the surface of the auxiliary shaft. The utility model seals the transmission gap through the first sealing member and the second sealing member, reduces the phenomenon of black spots caused by extrusion due to the entry of powder into the transmission gap, reduces product cost and quality risks, and prevents the entry of powder into the transmission gap to cause the situation of being too tight and difficult to disassemble.
